摘　　要：海流能转换器叶片翼型的水动力学性能优劣是海流能开发利用的关键因素。该文基于浙江工业大学水力学实验室设计的海流能转换器叶片,利用商用CFD模拟软件FLUENT对其叶片翼型在来流攻角从-4o～20o情形下的水动力特性进行了相应的数值模拟计算,得到翼型周围流场的速度分布、压力分布、翼型的失速特性以及水动力特性与攻角α的关系,可供设计高效的海流能转换器叶片时参考。The hydrodynamic performance of ocean current energy converter blade section foil is a key factor to exploit and utilize the ocean current energy.In this paper,based on the ocean current energy converter blade which is designed by the Hydraulics Laboratory of Zhejiang University of Technology,a numerical simulation using FLUENT software was carried out with various attack angle from-4o～20ofor the hydrodynamic characteristics of the blade section foil.Pictures of the velocity contours,velocity vectors,static pressure,stall and hydrodynamic characteristics around the foil versus attack anglesαwere obtained,which provide references for designing efficient current converter blades.
